dry.frog {AICcmodavg}R Documentation

Frog dehydration experiment on three different substrate types.

Description

This is a data set modified from Mazerolle and Desrochers (2005) on the mass lost by frogs after spending two hours on one of three substrates that are encountered in some landscape types.

Usage

data(dry.frog)

Format

A data frame with 121 observations on the following 16 variables.

Individual
a numeric vector
Species
a factor with levels Racla
Shade
a numeric vector
SVL
a numeric vector
Substrate
a factor with levels PEAT, SOIL, and SPHAGNUM
Initial_mass
a numeric vector
Mass_lost
a numeric vector
Airtemp
a numeric vector
Wind_cat
a numeric vector
Cloud
a numeric vector
cent_Initial_mass
a numeric vector
Initial_mass2
a numeric vector
cent_Air
a numeric vector
Perc.cloud
a numeric vector
Wind

log_Mass_lost
a numeric vector

Details

Note that the original analysis in Mazerolle and Desrochers (2005) consisted of generalized estimating equations for three mass measurements: mass at time 0, 1 hour, and 2 hours following exposure on the substrate.
